The new engines meet EPA Tier 4 and IMO Tier III Emissions standards (ABS Certification and Green Passport) without using a Selective Catalytic Reduction system (SCR) for exhaust gas after-treatment, thus eliminating the need to store or use urea aboard a vessel (see earlier story).

Cummins is integrating the five 12V250 engines into gensets designed to power Oceaneering's new vessel, MSV Ocean Evolution, a Marin Teknikk MT 6022 MSSCV design subsea construction vessel which is expected to launch at BAE Systems Mobile, AL, shipyard in early 2016.

"The GE Transportation team is very proud of this major milestone marking the first delivery of our Tier 4 emissions compliant diesel engines," said Afra Gerstenfeld, General Manager of Transportation's Marine group. "Our investment in this technology helps our customers meet their emissions requirements in the most efficient manner possible today."
